Clastic sedimentary rocks are classified according to...

• color

• location of formation

• grain size

• mineral composition

Which of the following is NOT an example of a clastic sedimentary rock?

• limestone

• conglomerate

• shale

• sandstone

A sedimentary rock made of different sized rounded sediments compacted together.

• shale

• sandstone

• siltstone

• conglomerate

How can you tell that this rock is breccia and not conglomerate?

• the sediments are all different sizes

• there is more clay in this rock

• the sediments are not rounded

• the sediments are lighter in color
